The invention relates to a method for producing a conductive contact part (10) for a detachable electric plug-in connection. Said method provides a contact element (20) comprising a bushing part (23), sections of which contain longitudinal slits and which has ribs (26) distributed around its periphery. A sleeve part (30), which can surround the bushing part (23) and cover the ribs (26), comprises two opposing end faces (31, 32). The sleeve part (30) is placed and positioned in an approximately coaxial manner in relation to the bushing part (23), in such a way that it covers the ribs, the positioned sleeve part (30) being locked by one of its two faces (31, 32) on the bushing part (23). The bushing part (23) is elastically twisted about its central axis (13), in such a way that the ribs (26) arc towards said central axis (13) and the other face (32, 31) of the sleeve part (30) is locked on the bushing part (23) that is held in a twisted position against the elastic restoring force of the ribs (26). A contact part (10), designed for mass-production, with defined elastic properties of the ribs (26) can thus be produced in a reproducible manner (10).
La présente invention concerne un procédé de production d'un contact conducteur (10) destiné à une fiche de raccordement électrique détachable. On obtient un élément de contact (20) qui comporte un élément douille (23) doté, par sections, d'une fente longitudinale et qui présente des lamelles (26) réparties sur sa circonférence. Un élément manchon (30), entourant l'élément douille (23) et recouvrant ses lamelles (26), comporte deux extrémités frontales (31, 32) opposées. L'élément manchon (30) est placé et positionné de manière approximativement coaxiale par rapport à l'élément douille (23) de telle manière qu'il recouvre ses lamelles. L'élément manchon (30) positionné étant arrêté par une extrémité (31, 32) sur l'élément douille (23) ; l'élément douille (23) se tordant de manière élastique autour de l'axe central (13) de telle manière que les lamelles (26) se courbent en arc vers l'axe central (13) et l'élément manchon (30) étant arrêté par l'autre extrémité (32,31) sur l'élément douille (23) qui est maintenu tordu à l'encontre de la force de rappel élastique des lamelles (26), on obtient un contact (10) ayant des lamelles (26) aux propriétés élastiques définies de manière reproductible pour la fabrication de grande série.
